It is necessary to creat a set of standards to control the use of pesticides which is consistent all over the world. After exposure to pesticides, pests can also have some changes, such as increased resistance to pesticides and the survival of pests may be passed on to the next generation. Due to the emergence of resistance, people have to increase the amount of medication and increase the number of drugs, the consequences of the pest caused by higher resistance. It leads to reduce crop production, have high cost of disease pests, environmental pollution and harmful human health. Therefore, the country governments have the responsibility to use the appropriate standard to prescribe the number of pesticides used and the dosage.

From the research, Since 1996, the EPA has been involved in international negotiations to control the use of DDT and other POPs in all parts of the world. Under

Since the 1970s, DDT has been banned globally and scientists have been able to detect DDT from many animals today. In 2001, the Stockholm Convention of United Nation Environmental program suggest to stop using the 12 chemicals include DDT.At the same time, there are signs of malaria in Africa because there is no suitable substitute.

After that, the voice for countries to use DDT as an important component of malaria control strategies is growing. African countries such as Tanzania and Uganda have begun to loosen their ban on
